Method related to sending management IP address and system

Abstract

A method includes a second system that determines a type of a first management Internet Protocol (IP) address, and sends, to a first system, first information used to indicate the type of the first management IP address; the first system determines the first management IP address based on the type of the first management IP address indicated by the first information, and releases a first correspondence between system identification information and the first management IP address to an advertisement system; the advertisement system sends the first correspondence to a network management system; and the network management system manages the first system based on the first correspondence.

What is claimed is: 
     
       1. A method implemented by a first system, wherein the method comprises:
 receiving, from a second system, first information indicating a first type of a first management Internet Protocol (IP) address of the first system; 
 determining the first management IP address based on the first type of the first management IP address; and 
 sending, to an advertisement system, a first correspondence that is between identification information of the first system and the first management IP address. 
 
     
     
       2. The method of  claim 1 , further comprising:
 receiving, from the second system, second information indicating a second type of a second management IP address of the first system; 
 determining the second management IP address based on the second type of the second management IP address; and 
 sending, to the advertisement system, a second correspondence that is between the identification information and the second management IP address, 
 wherein the second management IP address is an alternative switching address of the first management IP address. 
 
     
     
       3. The method of  claim 1 , wherein the second system and the advertisement system are a same system. 
     
     
       4. The method of  claim 1 , further comprising:
 sending, to the second system, a request packet for the first type of the first management IP address; and 
 receiving, from the second system in response to the request packet, a response packet comprising the first information. 
 
     
     
       5. The method of  claim 1 , further comprising receiving, from the second system, a Point-to-Point Protocol over Ethernet packet comprising the first information. 
     
     
       6. The method of  claim 5 , wherein the first information is either in a first extension field of a request packet in a PPPoE discovery phase or in a second extension field of a Network Control Protocol (NCP) request packet in a PPPoE session phase. 
     
     
       7. The method of  claim 1 , further comprising further determining the first management IP address from one or more generated management IP addresses based on the first type of the first management IP address. 
     
     
       8. The method of  claim 1 , further comprising generating the first management IP address based on the first type of the first management IP address. 
     
     
       9. The method of  claim 1 , further comprising further sending the first correspondence to the advertisement system based on a flood packet. 
     
     
       10. The method of  claim 9 , further comprising sending, the first correspondence to the advertisement system based on either opaque link state advertisement information of an Open Shortest Path First (OSPF) routing protocol or an extension field of an Intermediate System to Intermediate System (IS-IS) routing protocol. 
     
     
       11. The method of  claim 1 , comprising:
 identifying that the second system and the advertisement system are different systems; and 
 sending, in response to identifying that the second system and the advertisement system are different systems, the first correspondence to the second system. 
 
     
     
       12. A first system, comprising:
 a memory configured to store instructions; and 
 a processor coupled to the memory and configured to execute the instructions to cause the first system to
 receive, from a second system, first information is indicating a first type of a first management Internet Protocol (IP) address of the first system; 
 determine the first management IP address based on the first type of the first management IP address; and 
 send, to an advertisement system, a first correspondence that is between identification information of the first system and the first management IP address. 
 
 
     
     
       13. The first system of  claim 12 , wherein when executed by the at least one processor, the instructions further cause the first system to:
 receive, from the second system, second information is indicating a second type of a second management IP address of the first system; 
 determine the second management IP address based on the second type of the second management IP address; and 
 send, to the advertisement system, a second correspondence that is between the identification information of the first system and the second management IP address, wherein the second management IP address is an alternative switching address of the first management IP address. 
 
     
     
       14. The first system of  claim 12 , wherein the second system and the advertisement system are different systems. 
     
     
       15. The first system of  claim 12 , wherein when executed by the at least one processor, the instructions further cause the first system to:
 send, to the second system, a request packet for a for the first type; and 
 receive, from the second system in response to the request packet, a response packet comprising the first information. 
 
     
     
       16. The first system of  claim 12 , wherein when executed by the at least one processor, the instructions further cause the first system to further determine the first management IP address from one or more generated management IP addresses based on the first information. 
     
     
       17. A computer program product comprising computer-executable instructions that are stored on a non-transitory computer-readable storage medium and that, when executed by a processor, cause a first system to:
 receive, from a second system, first information indicating a first type of a first management Internet Protocol (IP) address of the first system; 
 determine the first management IP address based on the first type of the first management IP address; and 
 send, to an advertisement system, a first correspondence that is between identification information of the first system and the first management IP address. 
 
     
     
       18. The computer program product of  claim 17 , wherein the computer-executable instructions further cause the first system to:
 receive, from the second system, second information indicating a second type of a second management IP address of the first system; 
 determine the second management IP address based on the second type of the second management IP address; and 
 send, to the advertisement system, a second correspondence that is between the identification information of the first system and the second management IP address, wherein the second management IP address is an alternative switching address of the first management IP address. 
 
     
     
       19. The computer program product of  claim 17 , wherein the computer-executable instructions further cause the first system to:
 send, to the second system, a request packet for the first type; and 
 receive, from the second system in response to the request packet, a response packet comprising the first information. 
 
     
     
       20. The computer program product of  claim 17 , wherein the computer-executable instructions further cause the first system to further determine the first management IP address from one or more generated management IP addresses based on the first information.
